Sidetone Adjustment
The MS-4002 uses full-duplex audio (the same as a conventional telephone line) in which the talk and listen audio are sent and
received on the same line. When you talk on a channel, you hear your own voice in the speaker or headphones. This is called
sidetone. If you are using the MS-4002 with a microphone and speaker, sidetone could cause unwanted feedback, since the
microphone may pick up your returned voice audio and re-amplify it. This could also happen if you are using a headset where
the ear cushions do not completely cover the ears. In either of these cases, you should minimize the amount of sidetone.
NOTE: If you are using headphones that completely enclose the ears, a certain amount of your own voice level is
desirable to overcome the muffled sensation when talking.
To Adjust the Sidetone, do the following:
If you are using a speaker and microphone, or open-ear style headphones, adjust sidetone as follows:
1. Simultaneously press the All Talk and PA keys to activate the test tone.
2. Tap the channel 1 Call key to send the test tone on channel 1.
3. Increase the volume until you can hear the test tone
NOTE: For the volume control descriptions, see Figure 1, “MS-4002 Reference View,” on page 8.
4. Using a small, standard screwdriver, adjust the channel 1 sidetone (Figure 4) through the access hole in the bottom
of the MS-4002 to minimize the tone volume.
5. Tap the channel 1 Call key to turn off the test tone on channel 1 when finished.
6. Tap the channel 2 Call key, repeat the adjust for the channel 2 sidetone.
7. Tap any other key, except a Call key, to turn off the test tone when finished.
To set channels 3 and 4, do the following:
> Repeat steps 1 through 7, above.
